Question

A negative charge of 4.0 x 10 C and a positive charge of 7.0 x 10 C are separated by 0.15 m. What is

the force between the two charges?

Answer 1

112×10^12N

Step-by-step explanation:

We use the following equation to find the force between two charges that are away from each other at a particular distance:

F=k×q1×q2/r^2

F=9×10^9×4×10×7×10/(0.15)^2 F=252×10^11/0.225

F=1120×10^11=112×10^12
